Got the new wiper switch in today and it has three wires going to the motor, Blue with red, white, and black stripes. They are color coated to the motor so no big deal there. What throws me is on the motor the plug has 4 wires, the same three and one solid blue wire. I have no idea where the solid blue goes or what it does. I am not sure if the motor works, but I want to hook everything up correct before I start replacing motors. None of this was hooked up when I bought it, so no real guides there. Someone said that it goes to the dome light, but the way it hooks up to the motor makes me doubt it.
